Professional-Grade Solvent Ink Combining Vivid Color and Durability
Solvent Ink
For printed materials that remain visible for long periods—such as outdoor advertising, signage, and car wrapping—inks with excellent weather resistance and vivid color performance are essential.
DNP Fine Chemicals develops and manufactures solvent ink that delivers high durability and vibrant image quality through proprietary technologies. Compatible with a wide variety of substrates, our inks combine visual appeal with practical performance, greatly expanding the possibilities for outdoor expression.
What is Solvent Ink?
Solvent ink is an ink primarily composed of organic solvents and is mainly used in large-format inkjet printers for applications such as signage and advertising output.
Because it fixes to the media by slightly dissolving the surface, solvent ink offers excellent weather resistance and water resistance, making it highly durable against rain and ultraviolet light and ideal for outdoor use. It is compatible with a wide range of materials, including PVC and PET, and is also characterized by fast drying.
Main Applications of Solvent Ink
Solvent Ink offers excellent weather resistance and water resistance suitable for outdoor use and highly resistant to fading and degradation even when exposed to rain and ultraviolet light. In addition, it adheres firmly to plastic materials such as vinyl, films, and tarpaulin, enabling durable printed output.
Furthermore, its vivid color reproduction ensures high visibility even from a distance, resulting in eye-catching finishes. For these reasons, solvent ink is ideally suited for applications such as signage and advertising that are exposed outdoors for long periods.
■Main Applications of Solvent Ink
Rooftop signs, wall-mounted signs, freestanding signs, posters, POP Displays, illuminated signs, backlit signs, temporary construction fencing, banners, car wrapping, and more.
DNP Fine Chemicals’ Solvent Ink
DNP Fine Chemicals’ solvent ink is engineered with advanced performance designed for long-term outdoor use. It offers excellent resistance to ultraviolet light and weather exposure, maintaining vivid color reproduction even in outdoor environments over extended periods.
By controlling wetting and spreading behavior, bleeding is suppressed, enabling high-definition reproduction of fine text and smooth gradations.
In addition, a flexible ink design suitable for stretching applications such as car wrapping is employed, ensuring strong adhesion to plastic substrates. Its comprehensive performance—combining aesthetics, durability, and processability—is a key strength.
Features of DNP Fine Chemicals’ Solvent Ink
■Outdoor Weather Resistance
By using colored materials that are highly resistant to harsh environments such as ultraviolet light, rain, and wind, our solvent ink prevents fading and degradation over long periods of outdoor use. Through the use of weather-resistant resins and carefully selected additives, vivid color reproduction can be maintained even for outdoor signage and displays.
■High Image Quality
With vivid color reproduction and precise control of ink wetting and spreading behavior, bleeding and feathering are suppressed, enabling sharp reproduction of fine lines and text. The ink supports fine dot expression and smooth gradations, achieving high-definition, clear, and glossy image quality.
■Stretchability
Our solvent ink features a flexible ink design suitable for applications requiring stretching or printing on curved surfaces, such as car wrapping. It follows the expansion and bending of sheets while suppressing color fading and adheres firmly to plastic substrates, achieving both aesthetic quality and durability.
Core Technologies for Solvent Ink Development and Manufacturing
Precision Dispersion Technology
By uniformly dispersing pigments at the nanometer level, color performance, hiding power, and stability are enhanced. Aggregation and sedimentation are prevented, allowing quality to be maintained even during long-term storage, while suppressing nozzle clogging to achieve stable and reliable printing performance.
Resin Synthesis Technology
Through molecular design, we optimize binder resins that hold pigments and ensure adhesion to media. By adjusting weather resistance, flexibility, and adhesion, we impart outdoor durability and stretch-following properties required for applications such as car wrapping.
Evaluation and Analysis Technology
This technology quantitatively evaluates ink physical properties, weather resistance, and image quality to identify areas for improvement. Through methods such as spectroscopic measurement and accelerated weathering tests, performance is analyzed under conditions close to actual usage environments, leading to reliable product design.
Resist and Ink Formulation Technology
By optimizing the combination of solvents, resins, pigments, and additives, we achieve a well-balanced set of properties, including weather resistance, color performance, drying characteristics, and flexibility. Through designs tailored to specific applications and substrate characteristics, we address a wide range of market needs.
